I tried with the BETA and the official release. It was named mmc1 and mmc2 in both the BETA and the official release. For some reason my PC and 770 will not talk through USB, except when I flash. Now when I look at memory it says there is > 4 GB of data on it.

I just tried my 64 MB card that came with the 770 and it works fine when I look at memory, but my PC still does not recognize the 770 when I connect via USB. I think I will try to reformat my 1GB card some other way.

Any other thoughts would be appreciated - thanks for the info MikeB.

Update:
I was able to revert to the 2005OS and using wolfram's extrootfs suite I reformatted the card. That went fine. I then went back to the 2006OS and the card seems to be behaving just fine. I still cannot access it via my PC through the USB port. I am now creating 64MB of virtual memory, and that seems to be going just fine.

Another update:
It was unable to create the virtual memory on the card. It went all the way through and then it gave me the error. Back to the drawing board.

YAU:
OK - a reboot fixed that problem... Now I cannot connect to Gmail...
